Abstract
An inlaid centrifugal fan belongs to the technical field of the centrifugal fan and mainly comprises a spiral case and an electric motor; the output shaft of the electric motor is cooperated and connected with an end cover and an impeller. The utility model is characterized in that the whole electric motor is inlaid at the internal side of the spiral case to be arranged and the corresponding end cover has a special drawing structure and is cooperated correspondingly with the inlaid electric motor. The structure setting of product of the same variety is improved for the centrifugal fan, the centrifugal fan is ingeniously conceived, has reasonable and compact structure, consumes small space and maintains the advantages of large air quantity, high static pressure, low noise, etc and is widely used for the oil and smoke exhausting fan of various types.
Description
The utility model belongs to the centrifugal blower technical field.
The forward multiple wing formula centrifugal blower that is used for cooker hood at present, when equivalent diameter, its air quantity is big, static pressure is high and low noise and favored by the user.But because structural limitations, at least one halfbody of its motor is long-pending to expose to spiral case, causes whole blower fan height to increase, and is usually used in dark bell-type cooker hood, can't use on thin type or ultra-thin shape cooker hood.
The purpose of the utility model is to overcome the deficiencies in the prior art, improves by rational structure, and a kind of technological scheme of embedded centrifugal blower is provided.
Described embedded centrifuge mainly comprises spiral case, motor, and motor output shaft is connected cooperation with end cap, impeller, it is characterized in that whole motor embeds the inboard setting of spiral case, and corresponding end cap is special pull and stretch shape structure, cooperate corresponding with embedded motor.
This embedded centrifugal blower has improved the structure setting of existing like product, is skillfully constructed, compactness rational in infrastructure, and product takes up room little.And kept that air quantity is big, static pressure is high and advantage such as low noise, can be widely used in various types of cooker hoods.
Below in conjunction with Figure of description, the utility model is described in further detail.
Fig. 1 is embedded centrifugal blower structural representation.
As shown in FIG., spiral case 5 is provided with intake grill 3 and exhaust outlet 6, motor 2 whole embedding spiral cases 5 inboards, and be fixed on spiral case 5 inwalls.End cap 4, impeller 1 cooperatively interact, and are connected with the output axle head close-fitting of motor 2.Described end cap 4 is special pull and stretch shape structure, with embedded 2 corresponding cooperations of motor.Described impeller 1 adopts strong antecurvature multiple-airfoil type structure.This embedded centrifugal blower boundary dimension can be done very for a short time, can be applied to preferably in the thin type cooker hood.
Claims (2)
